Scheduled Maintainance

We have scheduled an upgrade of the Junos operating system on our main London firewall cluster. This upgrade is essential to ensure long-term availability and stability of the network. We expect minimal interruption to traffic not lasting more than a few seconds at a time, but the network is at risk for the entire window.

We have received a custom build of the Junos software that our firewalls run from Juniper which should correct the recent firewall issues we have experienced at our primary site.

We are planning to install this next Wednesday evening, and will aim to keep network disruption to a minimum. The network is at risk for the entire two hour window, but we anticipate the actual disruption will be under 10 seconds.

We apologise for any inconvenience caused by this essential maintenance.

We will be performing emergency maintenance this evening to upgrade our London firewalls to a new release of Junos that we have been provided with by JTAC. It is important that we install this as soon as possible in order to ensure network stability, so unfortunately we are not able to give more notice of this work.

Downtime is expected to be restricted to a few seconds, but the network is at risk during this window. We apologise for any inconvenience caused.

We will be performing scheduled maintenance to update the software on our VPN appliance.

The upgrade is expected to take around 15 minutes, during which remote access will not be available. Users may have to update ActiveX and Java components in their browsers after the upgrade is complete.

In conjunction with our vendor, Juniper Networks, we have identified a requirement to upgrade the operating system on our firewall cluster as soon as possible to ensure the continued stability of services.

This evening we will be re-integrating a failed cluster member into our firewall cluster and performing the operating system upgrade. This work will be done over a period of several hours and the network will be at risk during this time, but we hope any downtime will be restricted to only a few minutes.

We will be updating the software on our Juniper Secure Access appliance to the latest software to provide feature and security updates. All SSL VPN customers will be affected during this maintenance window, no other services should be affected.
